Introductory note

This introductory note does not form a part of the permit

This permit controls the operation of a waste incineration plant. The relevant listed activities are Section 5.1 A1 (b) and Section 5.4 A1 (b) (iii). The permit implements the requirements of the EU Directives on Industrial Emissions and Waste.

The main features of the permit are as follows:

The Energy Recovery Facility will accept up to 200,000 tonnes per annum of municipal, industrial and commercial waste for incineration in a combined heat and power (CHP) enabled Incinerator. Waste will be received in the waste reception hall where it will be discharged into a bunker for the temporary storage of waste. Waste will be mixed in the bunker and then fed into a feed hopper using an overhead crane.

The facility will process waste using air cooled, moving grate technology. The energy recovered from the combustion of waste will be utilised (in the form of high pressure steam) to produce electrical power through a steam turbine and generator unit. The facility will also have combined heat and power (CHP) capability through a blanking flange and heat/steam export from the turbine which can be utilised upon securing a suitable customer.

The key components of the technology will include, but shall not be limited to:

- A furnace/boiler unit incorporating moving grate technology and steam boiler with an energy recovery system;
- Flue gas treatment (FGT) system comprising selective non catalytic reduction (SNCR), semi dry reactor and bag house filters;
- Steam turbine/generator set with the capability for CHP operation;
- Condensate system, including air cooled condensers (ACC);
- Residue handling and storage facilities;
- Electrical equipment associated with the facility and its connection to the national grid;
- Continuous emissions monitoring system (CEMS); and
- Auxiliary equipment.

The combustion of waste will release flue gases which will be treated in order to comply with the requirements of the Industrial Emissions Directive.

Urea will be added at various stages of the boiler’s combustion chamber to reduce nitrogen oxides (NOx). Lime and powdered activated carbon (PAC) will be used within the FGT system. The lime reduces acid gas emissions while the activated carbon reduces mercury and the formation of dioxins/furans. The by-products from both reactions are captured in the fabric filter as Air Pollution Control Residues (APCR).

The facility will be designed to generate approximately 16.4MW and export approximately 14.4MW of electricity (assuming zero heat off-take). Incinerator Bottom Ash (IBA) will remain after the combustion of the waste. This ash will be discharged from the end of the combustion grate directly into an ash quench bath. Ash from the first to fourth boiler pass will discharge to the IBA Treatment Facility. Fly ash from the boiler fifth pass (economiser pass) is mixed with the hazardous fly ash to form the APCR, and will be conveyed to silos for storage prior to being sent off site for treatment or disposal.

The mixed ash will be transferred by means of conveyor to the IBA facility for weathering and processing. The ash will be processed into IBA aggregate (IBAA) and ferrous and non-ferrous metal recovery will take place.

The IBA treatment facility allows for the storage and management of the IBA from the ERF combustion process. The IBA facility will comprise a weathering area where untreated IBA will be stored before processing, and an IBA processing building containing machinery that will process the ash. The ash will be split into fine and coarse aggregate with ferrous and non-ferrous metals separated for recycling. The processed aggregates will be stored externally in segregated mounds against push walls.

The IBA facility has been designed with flexibility to handle ash volumes between 15% and 30% of the annual waste tonnage as IBA.

The site is located to the south east of the Dee Estuary within the Deeside Industrial Estate, 2km south west of the nearest village, Puddington. The site will be developed on an area of brownfield reclaimed land, once consisting of tidal mudflats of the Dee Estuary that was previously part of the Shotton Steelworks facility. WTI propose to construct new bespoke buildings to house the proposed waste management activities. Farmland and areas of open space lie approximately 50m to the north of the proposed permit boundary. The Borderlands railway line is adjacent to the east of the site. There are Sites of Special Scientific Interest (SSSIs), Special Areas of Conservation (SACs) and Inshore Special Protection Areas with Marine Components (ISPAMs) within 2km of the site boundary.

The site is centred on National Grid Reference SJ 310 716. The surrounding land use is predominantly industrial. Immediately adjacent to the site lies Shotton Power Station, UPM’s Paper Mill and Great Bear Distribution.

Access to the site will be via Weighbridge Road which runs parallel and adjacent to the western boundary of the site. Weighbridge Road can be accessed off the A548 located north of the site. The A548 links to the A494/A550 to the east of the industrial estate.

There are existing drainage ditches on site, and surface water drains running within 20m to the east and west of the site’s boundary. The status log of the permit sets out the permitting history, including any changes to the permit reference number.

Unless otherwise stated, any references in this permit to concentrations of substances in emissions into air means:

(a) in relation to emissions from combustion processes, the concentration in dry air at a temperature of 273K, at a pressure of 101.3 kPa and with an oxygen content of 3% dry for liquid and gaseous fuels, 6% dry for solid fuels; and/or

(b) in relation to emissions from non-combustion sources, the concentration at a temperature of 273K and at a pressure of 101.3 kPa, with no correction for water vapour content

(c) in relation to gases from incineration plants other than those burning waste oil, the concentration in dry air at a temperature of 273K, at a pressure of 101.3 kPa and with an oxygen content of 11% dry. For dioxins/furans and dioxin-like PCBs the determination of the toxic equivalence concentration (I-TEQ, & WHO-TEQ for dioxins/furans, WHO-TEQ for dioxin-like PCBs) stated as a release limit and/or reporting requirement, the mass concentrations of the following congeners have to be multiplied with their respective toxic equivalence factors before summing. When reporting on measurements of dioxins/furans and dioxin-like PCBs, the toxic equivalence concentrations should be reported as a range based on: all congeners less than the detection limit assumed to be zero as a minimum, and all congeners less than the detection limit assumed to be at the detection limit as a maximum. However the minimum value should be used when assessing compliance with the emission limit value in table S3.1.
